Blank Size when there is Corner Radius on Punch Solution

Follow our step by step solution on how to calculate Blank Size when there is Corner Radius on Punch?

FIRST Step Consider the formula

d bl = \sqrt{{d s}^{2} + 4 \cdot d s \cdot h shl - 0.5 \cdot r cn}

Next Step Substitute values of Variables

∴

d bl = \sqrt{{80mm}^{2} + 4 \cdot 80mm \cdot 2.15mm - 0.5 \cdot 0.003mm}

Next Step Convert Units

∴

d bl = \sqrt{{0.08m}^{2} + 4 \cdot 0.08m \cdot 0.0022m - 0.5 \cdot 3E-6m}

Next Step Prepare to Evaluate

∴

d bl = \sqrt{{0.08}^{2} + 4 \cdot 0.08 \cdot 0.0022 - 0.5 \cdot 3E-6}

Next Step Evaluate

∴

d bl = 0.0841813488844174m

Next Step Convert to Output's Unit

∴

d bl = 84.1813488844174mm

LAST Step Rounding Answer

∴

d bl = 84.1813mm
